    Analysis of the effect of the order of calving, calf sex and milk yield of cows on growth parameters of limousin calves
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Czerniawska-Piątkowska, Ewa; Wróbel, Agnieszka; Cioch, Cioch; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin
    The study was taken in the farm located in West Pomerania province where Limousine cattle in purity of breed were kept. The study included a total of 226 Limousine calves in purity of breed, which were born between 2011 and 2014. Data relating to the rearing of calves were obtained from breeding documentation carried out on the farm. Aim of work was to analyze the effect of order of calving, calf sex and milk yield of cows on growth parameters of Limousin calves. Analysis showed a significant (P ≤ 0.05, P ≤ 0.01) impact of subsequent calving on birth weight of calves. Calves born in the first calving achieved a significantly lower birth weight (32.4 kg) than calves born in next calving (2–4) (respectively, 36.5 kg, 37.3 kg, 37.9 kg). In the case of weaning weight and daily gains were found significant differences (P ≤ 0.01) between bulls and heifers. These factors in bulls were: 267.3 kg and 1093.3 g, while in heifers, respectively, 256.3 kg, 1048.7 g. There has been a significant impact of milk yield of cows on weaning weight and daily gains of calves. Calves whose mothers were characterized by higher milk yield (> 2000 kg) gained respectively 268.3 kg weaning weight and daily gain 1000.5 g. In the group of calves whose mothers were characterized by a lower milk yield (1501–2000 kg), these factors were respectively 244.8 kg and 993.2 g.

    The usage of transgenic animals in therapeutic proteins production
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Czerniawska-Piątkowska, Ewa; Brosędzki, Łukasz; Cioch, Barbara; Rzewucka-Wójcik, Edyta; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin
    Ability to create and use of transgenic animals can have a significant impact on many aspects of human life. These animals can improve medicine and provide new opportunities for the pharmaceutical or the food industry. The aim of this work is to collect available information about genetically modified animals, and the possibilities of their use in various areas of life and science. Aspects which are related to the use of transgenic animals as bioreactors for the production of proteins for therapeutic use will be discussed. The work will explain the concept of GMO, discuss the use of transgenic animals – what are benefits and risks that may be associated with it. The focus is primarily on the use of transgenic animals as bioreactors for the production of therapeutic proteins, the types of these proteins and their source of origin.
